Abstract:
Parallel Discrete Event Simulation (PDES) is a modelling technique that takes advantage of concurrent computing resources. However, its asynchronous nature can present challenges for efficient execution. This paper proposes a new non-blocking management system for handling messages and anti-messages in Time Warp simulations. This approach exploits the benefits of non-blocking algorithms to surpass the limitations of existing blocking mechanisms, resulting in more efficient and scalable simulations. Specifically, the approach relies on efficient atomic fetch-and-add operations provided by modern computer architectures for evaluating and updating the status of the event.
